Multilayer column header control method for list control

Abstract

The invention discloses a multi-layer column header control method for a list. The problems that in the prior art, multi-layer column header operation steps of a list control are complex, repeated operation is many, time is consumed, and working efficiency is reduced are solved. The method comprises the steps of establishing an operation area and a display area, and presetting a row of initial column headers in the display area; performing a column header adding and merging step by detecting an operation action in the operation area, and performing a column header deleting and merging step by detecting a deleting action in the display area. According to the method, the steps of adding and deleting the multi-layer column headers are simplified, the column headers can be automatically added and eliminated through one action of the click dragging operation and the deletion operation of a pointing device, and other column headers in the display area can be automatically arranged from top to bottom according to the area size; the height of the area is dynamically expanded and contracted, the superior-subordinate relation of the column header is automatically arranged, the number of repeated operations is greatly reduced, the operation time of workers is saved, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method for controlling multi-layer column headers of a list. Background technique [0002] List controls are widely used in report settings and data analysis operations. List controls generally have a multi-layer column header display form. The display form of multi-layer column headers has the following rules: each column header occupies the height of one row, and occupies one or more columns. The width of the column and the relationship between the upper and lower column headers are arranged according to the number of columns occupied, and the column headers occupying the most columns are arranged on top. However, the existing list control has the problems of complicated operation process and limited functions. [0003] Existing list controls include the following presentation methods: [0004] 1. Add a blank two-dimensional table (add several rows in advance) in th...
